I had a couple of good Sunday runs leading up to my week of tapering for the marathon. I bought a special belt which can store a small amount of wine gums and I wear it on the long runs. I am very pleased with this purchase. I hardly notice that I am wearing it and it doesn't move around while I run. It looks small, but I can actually cram in a lot of things. This belt full of sweet snacks and a small bottle of water have combined to make my long runs more manageable.
I did the Tate Britain run under these conditions last fortnight and my time improved by a full 20 minutes. I am still surprised by the variation.
The marathon is in two days. I will be happy if I can run the whole way. I am still undecided about my strategy to do this.
